RoLLGRiND|NG MACHINE.

Beit known that I, WILLAM M W ILHELML, a citizen of the United States', and a resident of the city and county of Kalamazoo, State of Michigan, have invented certain new and useful Improvements in Roll-Grinding Machines, of which the followingis a specification. f y This invention relates to improvements in roll-grinding machines. 5.

The objects of this invention are, first, to provide an-improved roll-grinding machine by which rolls of large size may be satisfactorily ground; second, to provide an improved roll-grind' machine bywhich such rollsas the rolls lpaper-makingimachines may be satisfactorily ground Without removing them'from the machines; third, to rovide an improvedv roll-grinding mac 'ne which may be `readily adjusted for grinding rolls of varying diameters; fourth, to provide an improved rollinding machine adapted to be adjusted so tat it produces the desired crowning of the rolls; fifth, to provide an.

improved roll-grinding machine which may be quickly adjusted to compensate for the wear of the grinding-wheel; sixth, to provide an improved roll-grinding machine which'is I comparatively simple'in construction, is very side. elevation view of my improved ro -grinddurable, and easy tomaniplate in use.

Further "objects and objects relating 4to structural details will definitely appear from the detailed description tol follow. Il accomplish the objects of my invention bythe devices 'and meansdescribed in the following specification.-

The invention is clearly defined, and pointed out in the claims. y

A structure embodying the features .of my invention is clearly illustrated in the accomspecification, in which- Figure 1 is a planview'oflmy improved roll-grinding machine shown in operative relation with a roll to be ground. Fi .2 is a ing mac ne. Fig. 3 is', an enlarged end elevation= ol my improved roll-grinding mavand-2... Fig. 5 is a detail plan'view showing the'supprt' and the means of horizontally.

In the drawin sthe sectional viewslare -taken looking in t 'edirection of the little arrows at the ends of the section-lines, and similar letters 4of reference refer-to similar parts throughout the several views. 4Referring to the drawings, I provide a wa preferably made .up of longitudinal rails A and cross-pieces A the rails A bein disposed Patented Sept. 11, 1906."

view showing the means for the vertical ad- 4at the corners, forming a rectangu ar frame.

The'longitudinal rails are braced at intervals with X-shaped brackets I, as clearly appears secured together. The way is further strengthened by the longitudinal truss-rods a. and a. VThe truss-rods-a which braceV the way laterally, are secured to the brackets which are mounted on the inner faces of in Fig. 4, so that they are firmly and rigidly the longitudinal rails A. These truss-rods Figs. -l and 4. .he truss-rods are arranged throu h the centrally-arran ed bracket a, (see ig. 1,) which forms t e truss-block. The truss-rods a prevent the horizontal sagging ofthe way. The way is adj ustably supported upon the standards B, which are provided with crossieces B', on which-it rests.4

The cross-pieces are adjustablyse'cured to the standards bymeans of bolts b, which are arranged through suitable slots b in the standard. (See Figs. 2 and 3.) The way is rigidly secured in position upon the crosspieces by the set-'screws b, Which are arranged through the upper ends of the stand- .ardsand enga e the bottom rails A.

airs, as clearly appears in A carriage ada ted to travel upon the v his carriage. sadapted to restupon the top rails of the way and is rovided with a downward extension atvthe ont, upon which the grinding-Wheel is adjustably secured. This downwardly-extendmg portion of the carriage bears upon the lowerinner rail` A. The grinding-wheel is supported upon the outward] -projecting arms C" of the bracket C. C is adjustablysecured to 'the carriage Cv by means of the screws @which are arranged through suitable slots c., in thebracket, and the set-'screws cf, which engage the bottom of .the bracket. The set-screws are arranged4 through suitably-projecting lugs cf on the carriage. (See Figs. 4 and 6.) By means of this vertical adjustment the grindingwheel v D may be properly adjusted to bringit to the his bracketl IOO IOS

center of the roll to be ground. The bearings E for the shaft D ofthe grinding-wheel are carried by the yoke E, which rests upon the arms C. Thls yoke is adjustable horizon- Abolts e, which are arranged through suitable slots e' in the yoke. (See Fi 5.) By this adjustment the grinding-whee isbrou ht into proper relation to the roll to be groun The carriage C is provided with the platform C upon which an electric motor, as G, is mounted T e motor is connected to the pulley D of `the grinding-wheel shaft by a vsuitable, belt,l as G. The carriage C is drivenb means of the screw bearing-shaft F, which 1s mounted in suitable bearings F onthe way. kThe screw-shaft F is provided with a-pulley F at one end, Which" 1s connected by means o-a suitable belt to the roll to be ground, as H. 2o (See Fig. 1.) 'Two belts are shown in the fig` ureto show that the shaft may be driven m either direction in this manner. The car- I'iage C is connected tothe driving-shaft'by means of the split nutf. (See Fig. 4.) The nut f thrown into and out of its eng-ag position by means of the lever f; w c is connected 'to the halves of the nut by the linksf `and f. These links are -pivoted to the lever on op osite sides of the pivot'- oint, so that b oth halves of t enut are either thrown together to engage the shaft or apart to release 1t. By

thereto, as desired. This .is of advantage, as some portions of a roll ma grinding than others. By re easing the drivmg-nut the carriage can .be readily reciprocated on the way. 'l A The roll II,in` relation'to which-I. have shown my improved roll-grindin machine,l is shown in conventional form. t is evident that such rolls as-e g., those of aper-making machines-may be them from the mac es.

I have shown'm'y improved grinder mounted upon the standardsB. I willstate., however, that lthe way is in some instances mount ed directly upon the frame of the paper-making machine. The out removing .them from the machineis of ve great advantage, as these rolls weigh severa tons, and when it is necessary-to remove them from thel machine a. large amount of time is consumed furthertha' that neces.

vsary for the actual operations. It is also vthen necessary to provide s eci'al mounts therefor. It is necessary in o r -er to ysecure good results-that theserolls be perectly ground-hat is,

' from end to end. Itis therefore necessary that the waybe very Otherwise itis likely to sag orto bow out, whichwill of course 'produce undesirable results, as the rolls to' be ground areofften twelve or fourteen feet tally by means of the set-screws e and the e operation of the lever 1 this arrangement the'carriage can be disengaged from its driving means or engaged require .more

ound wit outrexnoving ,of the rolls withuniformly ground length. It is sometimes desirable to grind the rolls crowning. I accomplish this by the adjustment of the way, bowing the same out slightly by means of the truss-rods a. By th1s means Iam enabled to secure the desired crownin and at lthe' same time have the roll unifor y and perfectly ground., By mounting the driving-motor for the grinding-wheel upon the carriage the same is independently drivenv and -without the aid of shafting, which is a very desirable feature.

By arran g the arts as I have illustrated and iidcribed am enabled to accurately adjust the machine to various sizes of rolls Iin varius positions. f It may also be quickly adjusted to compensate for the wear of the grinding-wheel in operation.

I have illustrated and described my imoved roll-grinding machine in detail 1n the orm preferred by me on account of its structural simplicity and conveniencein o eration. I am, however, aware that it is capable of considerable variation in structural details without departing from myinvention, ,and I desire 'to claim the same specifically as illustrated as well as broadly. Y Having thus described my inl'vention,what I claim as new, and desire to secure by Letters Patent, is-
